Congenital microphthalmos and anophthalmos are currently considered rare conditions. Many infectious agents have been previously associated with these pathologies, but rarely Treponema pallidum. We report a case of bilateral microphthalmos in which her mother presented gestational syphilis. [ABSTRACT FROM AUTHOR]

Temporomandibular joint (TMJ) dislocation can be classified into four groups (anterior, posterior, lateral, and superior) depending on the direction of displacement and the location of the condylar head. All the groups are rare except for anterior dislocation. 'Inverse' TMJ dislocation is a bilateral anterior and superior dislocation with impaction of the mandible over the maxilla; to the authors' knowledge only two cases have previously been reported in the literature. Inverse TMJ dislocation has unique clinical and radiographic findings, which are described for this case., (Copyright © 2011 International Association of Oral and Maxillofacial Surgeons.

An eruption cyst is an epithelial cyst of the oral mucosa. We report a case of a congenital eruption cyst successfully managed by removal of fluid from the cyst followed by close monitoring of the lesion until its remission once the teeth had erupted., (© 2010 Wiley Periodicals, Inc.)

Congenital pathologies are those existing at or dating from birth. Occurrence of congenital cystic lesions in the oral cavity is uncommon in neonates. Eruption cyst (EC) is listed among these unusual lesions. It occurs within the mucosa overlying teeth that are about to erupt and, according to the current World Health Organization (WHO) classification of epithelial cysts of the jaws, EC is a separate entity. This paper presents a case of congenital EC successfully managed by close monitoring of the lesion, without any surgical procedure or tooth extraction. Eruption of the teeth involved, primary central incisors, occurred at the fourth month of age. During this time neither the child nor mother had any complication such as pain on sucking, refusal to feed, airway obstruction, or aspiration of fluids or teeth.

Hymenoptera order includes bees, which have a stinging apparatus at the tail capable of delivering venom to the affected tissues. Myocardial infarction, acute renal failure, Necrotizing fasciitis, fatal infection and hemifacial asymmetry, are some of the unusual reactions reported following hymenoptera stings. This paper reports a case of bee sting in the right floor of the nose that mimicked an odontogenic infection affecting the upper lip, canine space and nasal cavity such as in cases of infection secondary to pulpal or periodontal pathology of the anterior teeth. After a thorough clinical and radiographic examination, odontogenic infection was discarded and the diagnosis of floor of the nose mucosal lysis and lip abscess secondary to a bee sting was made. This case was successfully managed with adequate incision, drainage and antibiotics without any further complication. There are several reports of unusual reactions following hymenoptera stings. However, just a few of them referred to infections of local reactions and none of them related to the anatomic location affected in the patient of the present case. Early diagnosis and treatment prevented infection dissemination and the likelihood of tissue necrosis as in previously reported cases of Necrotizing fasciitis.

Introduction: Systemic sickness can originate and proliferate alterations in the periodontium. The presence of Anti-neutrophil Cytoplasmic Antibodies (ANCA) in patients suffering destructive periodontal disease and systemic illness has been widely proven., Objective: To determine the existent relation between gingivitis and ANCA in children and adolescents suffering from leukemia. These patients were examined at the Autonomous Services of the University Hospital in Maracaibo, Venezuela, and at the Hospital of Pediatrics Foundation in Zulia State, Venezuela., Materials and Methods: 40 patients ranging from 6 to 16 years of age were included in a controlled study. 20 patients suffering from acute leukemia constituted an experimental group, and 20 more patients without apparent systemic sickness who formed a control group. All 40 patients underwent clinical evaluation, and periodontal tissue radiographic evaluation and assessment of ANCA through an enzyme-linked immunoasorbent assay (ELISA); this was done using an IMMCO Diagnostic commercial kit., Results: No Significant differences in the gingivitis average index, plaque and bone loss between the experimental and the control group were evidenced. A significant correlation between gingivitis and ANCA was not evidenced either. Nevertheless, 7 out of 20 patients of the experimental group turned out to be ANCA positive. In contrast, no positive cases were reported in the control group. (p < 0.05 Fisher Test)., Conclusion: The results of this study suggest that the presence of ANCA is probably related to ongoing immune alterations in patients suffering from leukemia but not related to gingivitis.
